Abstract
A vehicle power transmission device includes: a first power transmission member including a cylindrical shaft end portion rotatably supported via a first bearing on an inner circumferential side of a non-rotating support wall; and a second power transmission member supported on the inside of the cylindrical shaft end portion via a second bearing radially overlapping with the first bearing by the cylindrical shaft end portion to be rotatable concentrically and relatively to the first power transmission member, the second power transmission member including a circular disc gear portion protruded to an outer circumferential side at a predetermined distance from the second bearing in a shaft center direction of the second power transmission member, at a portion facing the first bearing, the gear portion having an annular inner circumferential guide protruding portion for guiding to the first bearing a lubricant oil that passes through the second bearing for lubrication, that enters into a gap between the second bearing and the gear portion, and that travels to the outer circumferential side due to the centrifugal force.
